Vacuum hose adaptor

Abstract

A vacuum hose adaptor ( 20 ) having a suction air channel ( 24 ) defined between a sealing plate ( 25 ) and a male hose coupler ( 22 ). The sealing plate ( 25 ) is designed to make a relatively air tight seal against the bottom plate ( 58 ) (i.e., rotary brush opening, suction inlet) on the bottom of a main nozzle ( 55 ) on an upright vacuum cleaner ( 50 ) and may use one or more locking mechanisms ( 26 ) for temporarily holding the sealing plate ( 25 ) against the bottom plate ( 58 ) of the main nozzle ( 55 ). A vacuum hose ( 60 ) can be removably attached to the male hose coupler ( 22 ) so that suction air produced by the upright vacuum cleaner ( 50 ) can be conducted from the upright vacuum cleaner ( 50 ) through the main nozzle ( 55 ), through the suction air channel ( 24 ), through the male hose coupler ( 22 ) and through the vacuum hose ( 60 ) for use.

What is claimed is: 
     
       1. A vacuum hose adaptor for removable attachment to a main nozzle of a vacuum cleaner, comprising:
 an adaptor body, comprising a front, a back, a top and a bottom, wherein a suction air channel and a sealing plate are defined on the top of the adaptor body; 
 a vacuum hose coupler attached to the front of the adaptor body and in suction communication with the suction air channel and configured to be removably attached to a flexible vacuum hose; 
 a pair of swivel wheels that are attached to the bottom of the adaptor body at an angle with respect to the sealing plate; 
 a locking mechanism configured to engage a main nozzle of a vacuum cleaner during use to removably secure the front of the adaptor body against the main nozzle; wherein suction air can be communicated between the main nozzle and the suction air channel during use of the vacuum cleaner, and 
 a pivotal arm assembly comprising a pivotal arm with a tip; wherein the pivotal arm is configured to be movable between a stowed position and a high-speed position, wherein the tip is configured to engage a high-speed switch on the vacuum cleaner when the pivotal arm is in the high-speed position. 
 
     
     
       2. The vacuum hose adaptor of  claim 1 , wherein the adaptor body comprises a left side with a left guide and a right side with a right guide, wherein the left and right guides extend above the sealing plate and are configured to engage a left and right side of the main nozzle respectively. 
     
     
       3. The vacuum hose adaptor of  claim 1 , wherein the sealing plate comprises a gasket bonded to the sealing plate, wherein the gasket is configured on the sealing plate to form a seal between the sealing plate and the main nozzle of the vacuum cleaner. 
     
     
       4. The vacuum hose adaptor of  claim 1 , wherein the locking mechanism comprises:
 one or more attachment bracket at the back of the adaptor body configured to engage a back portion of the main nozzle; and 
 one or more locking pins at a front portion of the adaptor body configured to removably secure the front portion of the adaptor body to a front portion of the main nozzle. 
 
     
     
       5. The vacuum hose adaptor of  claim 1 , wherein the adaptor body comprises a stowed indent that is configured to engage the pivotal arm when in the stowed position. 
     
     
       6. The vacuum hose adaptor of  claim 1 , wherein the adaptor body comprises a high-speed indent that is configured to engage the pivotal arm when in the high-speed position. 
     
     
       7. The vacuum hose adaptor of  claim 1 , wherein the pivotal arm is further configured to include a low-speed position. 
     
     
       8. The vacuum hose adaptor of  claim 7 , wherein the adaptor comprises a low-speed indent that is configured to engage the pivotal arm when in the low-speed position. 
     
     
       9. A vacuum hose adaptor for removable attachment to a main nozzle of a vacuum cleaner, comprising:
 an adaptor body, comprising a front, a back, a top, a bottom, a left guide and a right guide, wherein a suction air channel and a sealing plate are defined on the top of the adaptor body and the left and right guides extend above the sealing plate and are configured to engage the main nozzle; 
 a vacuum hose coupler attached to the front of the adaptor body and in suction communication with the suction air channel and configured to be removably attached to a flexible vacuum hose; 
 a pair of swivel wheels that are attached to the bottom of the adaptor body at an angle with respect to the sealing plate; 
 a locking mechanism configured to engage a main nozzle of a vacuum cleaner during use to removably secure the front of the adaptor body against the main nozzle; wherein suction air can be communicated between the main nozzle and the suction air channel during use of the vacuum cleaner, and 
 a pivotal arm assembly comprising a pivotal arm with a tip; wherein the pivotal arm is configured to be movable between a stowed position and a high-speed position, wherein the adaptor body comprises a stowed indent that is configured to engage the pivotal arm when in the stowed position. 
 
     
     
       10. The vacuum hose adaptor of  claim 9 , wherein the adaptor body comprises a high-speed operational indent that is configured to engage the pivotal arm when in the high-speed position. 
     
     
       11. The vacuum hose adaptor of  claim 9 , wherein the pivotal arm is further configured to include a low-speed position. 
     
     
       12. The vacuum hose adaptor of  claim 11 , wherein the adaptor comprises a low-speed indent that is configured to engage the pivotal arm when in the low-speed position. 
     
     
       13. The vacuum hose adaptor of  claim 9 , wherein the sealing plate comprises a gasket bonded to the sealing plate, wherein the gasket is configured on the sealing plate to form a seal between the sealing plate and the main nozzle of the vacuum cleaner. 
     
     
       14. The vacuum hose adaptor of  claim 9 , wherein the locking mechanism comprises:
 one or more attachment bracket at the back of the adaptor body configured to engage with a back portion of the main nozzle; and 
 one or more locking pins at a front portion of the adaptor body configured to removably secure the front portion of the adaptor body to a front portion of the main nozzle. 
 
     
     
       15. The vacuum hose adaptor of  claim 9  wherein the tip is configured to engage a high-speed switch on the vacuum cleaner when the pivotal arm is in the high-speed position. 
     
     
       16. The vacuum hose adaptor of  claim 9  further comprising a friction block configured to allow the pivotal arm to be positioned in any location between the stowed position and the high-speed position.
